Scroll wheel behavior on Tag Panel

[Florian]

First of all, I agree that the behavior is not optimal. I think it's very obvious from @redux's post above. However, I'm not sure about what the optimal behavior might be, because there are always different interests at stake.

The list box should not scroll or change content unless you select the "down" arrow at the right end of the list box and deliberately select a different value, or if you intentionally type in different information.

Preventing scrolling in this case would disrupt the workflow for all those that simply click into the field and use the scroll wheel (or two-finger scrolling) and expect the field to cycle through the different values. Also, typing is intentionally disabling scrolling to address [F] Tag Panel problems with 'wheel mouse' - #10 by JJ_Johnson.

In Office, when you start a two fingered scroll over any part of a scrollable dialog, the whole dialog scrolls, irrespective of whether you start with the cursor over a dropdown box or not, or whether the dropdown box has the focus. If you want to scroll a dropdown contents with the mouse, you click it to give it the focus, then single finger scrolling works (incidentally, the down-arrow gets a border to show it will get the focus if you click when the mouse is over it). Two-finger scrolling still scrolls the containing dialog. To me, this feels intuitive and consistent with what I normally see in the Windows interface.

I don't have Office, so it's a little bit hard to imagine. What do you mean by single finger scrolling? It sounds like this is just moving the mouse cursor, but it's probably a special feature of your touchpad. Do you know the equivalent of that when using the mouse?

One tricky bit is that the Tag Panel background can't get the focus by itself, there is always one field that has the focus. I prefer to keep it that way for all those who are mainly using the keyboard to navigate between the different UI parts.
